SPECIFICATION forming part Of Letters Patent NO. 653,106, dated July 3,1900. Application filed April 28, 1900. Serial No. 14,705. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM MAX, acitizen of the United States, and aresident of the city of New York, borough of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved Strapping-Tool, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved tool forconveniently and quickly drawing or stretching metal straps across theside of a box or other receptacle previous to nailing the strap down,the tool being adapted for securely holding the strap in a stretchedposition, so that the operator may use both hands for nailing purposes.

The invention is embodied in the construction and combinationhereinafter.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a perspective view of the improvement as applied. Fig. 2 isan enlarged sectional side elevation of the same. Fig. 3 is a similarview of the same with the tool in a different position. Fig. 4 is aninverted plan view of part of the tool, and Fig. 5 is a transversesection of the same on the line 5 5 in Fig. 3.

On a suitable handle A is formed a fixed jaw B, operating in conjunctionwith a movable jaw O for engaging and gripping the strap D to be drawnor stretched across the side of a box E, as is plainly indicated inFigs. 1, 2, and 3. The movable jaw O is pivoted to the fixed jaw B andis provided with a tailpiece O, engaged at the under side by the foot orshank F of a segmental block F which serves as a fulcrum for the toolwhen in use. The said block F is toothed on its outer side and fittedlooselyin a socket formed in the under side of the handle A. The shank Fpasses through and slides freely in a transof parts, as described Versehole or slot formed in the handle directly in rear of the pivot or jointof the movable jaw. The relation of parts is such that the grippingedges of the jaws meet before the fulcrum-block F reaches the bottom ofits socket, so that the shank F will always abut and exert leverage onthe movable jaw 0 when the tool is in use.

Now in order to use the tool the operator takes hold of the handle A andpresses with his finger on the tailpiece O of the movable jaw 0, so asto open the latter and engage the strap D at or near the end of the sideof the box over which the strap is to be stretched. The operator nowplaces the segmentaltoothed face F 'of the block F against the adjacentside of the box, as indicated in Figs. 1 and 2, and then presses down onthe handle A, so that the block F is caused to slide inward and press onthe tailpiece O, and thereby impart a swinging motion to the movable jawC, so as to close the same tightly upon the strap D, whereby the latteris firmly gripped by the fixed jaw B and the movable jaw 0. Upon theoperator bearing down further on the handle A the jaw end of the toolswings outward away from the box, as; the block F forms a fulcrum forthe tool to swing on, and consequently the strap D is drawn across thebox and stretched very tight over the surface thereof. The handle A whenswung downward and inward toward the side of the box will firmly holdthe strap D in a stretched position, and the operator can now releasethe handle A and use both hands for nailing the stretched portion of thestrap over the corresponding side of the box. When this has been done,the operator again takes hold of the handle A and swings the same upwardand presses the tailpiece O to open the jaw for releasing the strap.

From the foregoing it will be seen that the tool is very simple anddurable in construction and can be readily manipulated by the operatorto firmly and properly stretch the strap over the side of a box or otherreceptacle to permit of nailing the strap down when in a stretchedposition.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent- As an improved article of manufacture, thedescribed tool for use in strapping boxes, (5 30., the same beingconstructed of an elongated handle and a fixed gripping-jaw which areformed integrally, a short movable jawpivoted to the fixed one, andprovided with a tailpiece extending back on the handle, and

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
